So HN comment history contributes to the application process? It makes sense, but as a lurker I have to admit I'm a little unsettled by it. It makes me wonder if my tendency to take a backseat and only raise my hand if I'm sure what I have to say is relevant and has not already been said, is somehow an indicator about my likelihood of success as an entrepreneur?
I wouldn't sweat it. I think I had almost no karma when we applied.
I don't think it hurts you as much as it can possibly help you. If you have lots of intelligent comments, it's one more reason to put you in the "interview" pile. I think only a few people in our round had notable HN records.
I think quality trumps quantity. I would think if a user posted tonnes of sub-average comments, it may hurt him. And if a user posted a dozen comments of value, it could be a plus.
